FLOOR POLISH Application filed ma as, 1921. Serial no 471,883.

' To all whom it may concern:

Be it known that I, WILLIAM H. HUGHES, a citizen of the United States, and a resident of Falls City, in the county of Richardson and State of Nebraska, have invented certain new and useful Improvements in Floor Polishers, of which the following is a specification.

This invention relates to polishers especially adapted for use on floors.

An important object of this invention is to provide a floor polisher having novel means whereby a plurality'of polishing elements such as brushes are yieldingly pressed I into contact with the floor and rotated so as to provide the floor with the desired finish.

Other objects and advantages of the invention will-be apparent during the course of the following description.

In the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 1s a perspective of the improved floor polishing device.

Figure 2 is a central vertical longitudinal sectional view through the improved floor polisher.

Figure 3 is a plan view of the same.

Figure 4 is a section taken on line 4-4 of Flgure 2.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 5 generally designates the improved floor polisher which-includes spaced parallel side walls 6 having their rear ortions extended upwardly to form the slde walls of a compartment 4 within which an electric motor 8 is arranged. The bottom of the compartment 7 is indicated by the numeral 10 and consists preferably of a piece of sheet metal provided with downwardly directed ears 11 secured to the sides 6 of the device. The motor 8 is flatly mounted upon the bottom 10 and has connection with electric wires 12 which may be connected by means of the usual plug with an electric light socket or the like.

A polishing element in the form of a brush 14 of any desired construction is arranged at the forward portion of the device and is provided with a shaft 15 having its ends journaled in bearings 16 which may be slidable within vertical guides 7 8. The polishing member 14 may be in the nature of a fabric roll or the like and isespecially adapted for providing a high polish or finish on the floor. The bearings 16 which may be of any desired type are pressed upwardly by coiled springs 17 and downwardly by coiled springs 18, the upper coiled springs 18 being stronger than the lower coiled springs 17 whereby the rotary polishing element 14 is yieldably pressed into engagement with the floor so as to provide the floor surface with the desired finish. The weight of the device however, tends to lessen the pressure of the-coiled springs 18. With reference to Figure 4 it will be observed that the lower portions of the side walls 6 are formed with inwardly directed flanges 20 which constitute stop elements for the ends of the coiled springs 17 and also an attaching means for castors designated by the numeral 21.

The polishing element 14 is rotated by means of a sprocket chain 23 trained about a sprocket wheel 24 secured on the shaft 15 and about a second sprocket wheel 25 keyed or otherwise secured to the armature shaft of the electric motor 8.

The improved polishing device is provided with a second rotary cleaning member 28 having its shaft 30 journaled inbearings similar to the bearings 16, which bearings are positioned by means of coiled springs correspondingin construction to the coiled springs 17 and 18.

The rotary motion of the forward polishing element 14 is transmitted to the rotary element 28' by means of a sprocket chain 32 trained about a sprocket wheel 35 secured on the shaft 15 and about a sprocket wheel 36 keyed or otherwise secured to the shaft 30. As illustrated particularly in Figures 1 and 2 the rotary polishing element 14 is extended beyond the forward ends of the sides 6 and the top 40 so that if desired the sides of a wall or more particularly the base boards of a room may be cleaned or polished.

In the use of the device the same may be moved along the floor or other surface to be cleaned b means of a handle 44 having forwardly directed sides 46 adjustably connected to the sides 6 of the device. Since the forward portion of the improved polisher is comparatively fiat the device may be operated beneath articles of furniture having portions which lie close to the floor.

In carrying out the invention the polishing elements 14 and 28 may be of any material such as felt or wool and the two polishing elements may be of the same or difl'erent material, this feature forming no part of the invention.

Having thus described the invention what I claim 1s:

A device of the character described com prising a body provided with spaced side walls havin their opposed sides formed with vertica ly arranged guides, polishing elements having shafts rovided with bearings slidable in said gui es, upper and lower springs received in said guides and contacting with opposite sides of said bearings the nected to said inwardly directed flanges,

and an electric motor mounted on the top for operating said polishing elements, the upper springs being greater in strength than the lower springs, whereby to urge the polishing elements into engagement with the floor.

WILLIAM H. HUGHES.
